The Aircraft Integrated Meteorological Measuring System 20 Hz(AIMMS-20) has been used by the Hong Kong Observatory(HKO),China in data collection for tropical cyclone situations over the South China Sea and windshear and turbulence measurement at the Hong Kong International Airport(HKIA).This paper discusses possible methods for further enhancing the quality of the wind and temperature measurements from the *** wind measurement,the enhancement methods include:error modelling of the accelerometer(e.g.,bias offset and cross-axis rate sensitivity),global positioning system(GPS) phase lag consideration,better representation of the inertial measurement unit(IMU) velocity based on the GPS velocities and considering their location differences,consideration of the slower update of GPS velocity,and wing *** temperature measurement,the methods include the consideration of the temperature sensor response and the sensor housing *** results of typical flights using AIMMS-20 show that the accuracy of the wind and temperature data could be improved by 20%-30%.Though the discussion in the present paper is related mainly to a specific meteorological measuring system on a particular aircraft,the techniques so employed should be a useful reference for similar systems installed on other aircraft.

E-commerce systems for construction material procurement are becoming increasingly important in Hong Kong. These E-commerce systems are non-interoperable and create problems for the buyers who use these systems to purchase construction materials. This paper presents the mobile agent-based approach and web services-based approach for enabling interoperation of these systems in the E-Union environment.

Currently, there are a limited number of dynamic models available for braided composite plates with large overall motions, despite the incorporation of three-dimensional(3D) braided composites into rotating blade components. In this paper, a dynamic model of 3D 4-directional braided composite thin plates considering braiding directions is established. Based on Kirchhoff's plate assumptions, the displacement variables of the plate are expressed. By incorporating the braiding directions into the constitutive equation of the braided composites, the dynamic model of the plate considering braiding directions is obtained. The effects of the speeds, braiding directions, and braided angles on the responses of the plate with fixed-axis rotation and translational motion, respectively, are investigated. This paper presents a dynamic theory for calculating the deformation of 3D braided composite structures undergoing both translational and rotational motions. It also provides a simulation method for investigating the dynamic behavior of non-isotropic material plates in various applications.

BACKGROUND: Multi-visceral resection for extra-pancreatic carcinoma is an uncommon procedure that may offer palliation and potential cure but must be balanced against the risk for morbidity and mortality. METHODS: A retrospective analysis was made of patients who had undergone multi-visceral resection of non-pancreatic carcinoma. Factors influencing this procedure included histology,pathologic confirmation of pancreaticoduodenal invasion, tumor clearance, peri-operative morbidity and ***: Sixteen patients had en bloc resection including a whipple procedure (6 patients) and a distal resection (10).Primary pathology mostly originated from the stomach and adenocarcinoma was predominately histological. An R0 resection was made in 13 patients, and actual cancer invasion or abutment into the pancreas or duodenum was confirmed pathologically in 11 patients. Twelve patients suffered from at least one complication. Ten patients required therapeutic intervention for complications. There were 2 in-hospital *** median survival of deceased patients was 7.5 months. Six patients are alive at a median of 21 months, and 4 patients have no evidence of disease to the present. CONCLUSIONS: Multi-visceral resections for extra-pancreatic carcinoma are associated with substantial morbidity that requires therapeutic intervention. Clinical determination of pancreaticoduodenal abutment and achievement of tumor clearance is excellent. Survival with and without recurrent disease is often limited, supporting that it is necessary to cautiously perform the aggressive procedures in consideration of neoadjuvant therapy.
